I had a structural worry about the relation of Gaita’s three chapters on truth, interesting though these chapters are, to the rest of Gaita’s project. And I had some residual questions left after reading the book: What are persons? How do we know when we are encountering one, and when are we justified (we must be sometimes: compare the various sorts of animal) in a decision that something we encounter is not a person? Do evil actions always involve a sort of blindness to what is being done? If so, how easy is it to explain how agents who do evil can be held responsible for their cognitive deficiencies? These may of course be questions that Gaita was not trying to answer; but in any case, as I hope I have conveyed, I found A Common Humanity a striking and revelatory read, and I warmly recommend it.
